Jefferson Lab injector development for next generation parity violation experiments
To meet the challenging requirements of next generation parity violation experiments at Jefferson Lab, the Center for Injectors and Sources is working on improving the parity-quality of the electron beam. These improvements include new electron photogun design and fast helicity reversal of the Pockels Cell. We proposed and designed a new scheme for slow helicity reversal using a Wien Filter and two Solenoids. This slow reversal complements the insertable half-wave plate reversal of the laser-light polarization by reversing the electron beam polarization at the injector while maintaining a constant accelerator configuration. For position feedback, fast air-core magnets located in the injector were commissioned and a new scheme for charge feedback is planned.
